Anne Sexton

Plath befriended Anne Sexton when they were studying in Robert Lowell's poetry class. Sexton became another respected, though less well known poet, and like Plath, she too committed suicide. The following poem (Sylvia's Death) was Sexton's response to the news that Plath had killed herself. It is worthy of study in its own right, and has many allusions to their friendship as well as other American poets/poetry. I would single out the sense of ownership of Death suggested by the use of italics and would point you at e.e. cummings' fascinating poem "Buffalo Bill's / defunct" as a possible allusion.
Sexton's work is also considered confessional, and has some similarities with Plath's work. Another of Sexton's poems worth looking at is Dr Martin.

Sylvia's Death

for Sylvia Plath

O Sylvia, Sylvia,
with a dead box of stones and spoons,

with two children, two meteors
wandering loose in a tiny playroom,

with your mouth into the sheet,
into the roofbeam, into the dumb prayer,

(Sylvia, Sylvia
where did you go
after you wrote me
from Devonshire
about raising potatoes
and keeping bees?)

what did you stand by,
just how did you lie down into?

Thief --
how did you crawl into,

crawl down alone
into the death I wanted so badly and for so long,

the death we said we both outgrew,
the one we wore on our skinny breasts,

the one we talked of so often each time
we downed three extra dry martinis in Boston,

the death that talked of analysts and cures,
the death that talked like brides with plots,

the death we drank to,
the motives and the quiet deed?

(In Boston
the dying
ride in cabs,
yes death again,
that ride home
with our boy.)

O Sylvia, I remember the sleepy drummer
who beat on our eyes with an old story,

how we wanted to let him come
like a sadist or a New York fairy

to do his job,
a necessity, a window in a wall or a crib,

and since that time he waited
under our heart, our cupboard,

and I see now that we store him up
year after year, old suicides

and I know at the news of your death
a terrible taste for it, like salt,

(And me,
me too.
And now, Sylvia,
you again
with death again,
that ride home
with our boy.)

And I say only
with my arms stretched out into that stone place,

what is your death
but an old belonging,

a mole that fell out
of one of your poems?

(O friend,
while the moon's bad,
and the king's gone,
and the queen's at her wit's end
the bar fly ought to sing!)

O tiny mother,
you too!
O funny duchess!
O blonde thing!

Dr. Martin

You, Doctor Martin, walk
from breakfast to madness. Late August,
I speed through the antiseptic tunnel
where the moving dead still talk
of pushing their bones against the thrust
of cure. And I am queen of this summer hotel
or the laughing bee on a stalk

of death. We stand in broken
lines and wait while they unlock
the doors and count us at the frozen gates
of dinner. The shibboleth is spoken
and we move to gravy in our smock
of smiles. We chew in rows, our plates
scratch and whine like chalk

in school. There are no knives
for cutting your throat. I make
moccasins all morning. At first my hands
kept empty, unraveled for the lives
they used to work. Now I learn to take
them back, each angry finger that demands
I mend what another will break

tomorrow. Of course, I love you;
you lean above the plastic sky,
god of our block, prince of all the foxes.
The breaking crowns are new
that Jack wore.
Your third eye
moves among us and lights the separate boxes
where we sleep or cry.

What large children we are
here. All over I grow most tall
in the best ward. Your business is people,
you call at the madhouse, an oracular
eye in our nest. Out in the hall
the intercom pages you. You twist in the pull
of the foxy children who fall

like floods of life in frost.
And we are magic talking to itself,
noisy and alone. I am queen of all my sins
forgotten. Am I still lost?
Once I was beautiful. Now I am myself,
counting this row and that row of moccasins
waiting on the silent shelf.
